Biomechanical cues verified by the PlanWorkouts Science Review Board under CSCS editorial oversight; see our editorial standards.
The Weighted One Hand Pull Up is a compound back movement designed to train the Lats with direct engagement of the Forearms.
Sagittal/transverse plane shoulder horizontal extension and scapular retraction. Strengthens upper back, rhomboids, and rear deltoids while demanding lower back stability. Executing this with strict form maximizes muscle fiber recruitment while protecting joint structures.
Quick Exercise Facts
Target Muscle Activation
A one-arm pull-up is already an elite-level strength benchmark most lifters never reach; adding weight on top of that puts this firmly in the realm of advanced calisthenics athletes rather than general training. It demands not just lat and bicep strength but serious core and grip stability to keep the body from rotating during the pull. This is a goal to build toward over years, not a standard accessory exercise.
How to Do the Weighted One Hand Pull Up
- Grip the pull-up bar with an overhand grip, slightly wider than shoulder width.
- Hang from the bar with your arm fully extended and your body straight.
- Brace your core and pull your body up toward the bar by bending your elbow and squeezing your back muscles.
- Continue pulling until your chin clears the bar.
- Lower your body back down to the starting position with control.
- Continue for the set reps, taking care to lower with control and reset your posture between each rep.
Recommended Sets & Reps by Training Goal
70–80% 1RM · 90–120s rest
85%+ 1RM · 2–3 min rest (Calc 1RM)
50–60% 1RM · 45–60s rest
Biomechanical & Joint Load Cues
Sagittal/transverse plane shoulder horizontal extension and scapular retraction. Strengthens upper back, rhomboids, and rear deltoids while demanding lower back stability.
Common Mechanical Mistakes & Form Errors to Avoid
- Using Torso Momentum (Jerking): Rocking the upper body aggressively to initiate the pull relies on hip extension rather than the latissimus and rhomboids.
- Incomplete Scapular Retraction: Failing to pull the shoulder blades together at the top cuts off peak contraction of the rhomboids and middle trapezius.
- Flaring Elbows Too Wide: Letting elbows flare 90 degrees shifts mechanical tension away from the lats onto the upper traps and neck.
Proper Breathing Patterns & Core Engagement
Inhale as weight lowers forward. Pull elbows back past torso while exhaling and squeezing shoulder blades together.

Injury Modification & Joint Safety
For lifters with lower back fatigue, chest-supported incline rows or seated cable rows provide equivalent upper-back hypertrophy without spinal loading. If joint irritation persists, immediately stop and substitute this movement with another exercise from the Back exercises category.
Muscles Worked
The Weighted One Hand Pull Up primarily targets the Lats, with Biceps as the primary synergist muscle group, along with the Forearms.

FAQ
- What muscles does the Weighted One Hand Pull Up work?
- The Weighted One Hand Pull Up primarily targets the lats as the primary agonist. Synergist assistance is provided by the biceps along with the forearms. Maintaining strict biomechanical alignment ensures maximal tension remains focused on the intended muscle fibers rather than shifting to surrounding stabilizer joints.
- What equipment do I need for the Weighted One Hand Pull Up?
- The Weighted One Hand Pull Up is performed using a weighted. Ensure all equipment is securely positioned with collars or safety pins locked before loading working sets. If you train in a home gym or minimal setup, explore our equipment-free and resistance band alternatives below.
- What is the most common form mistake on the Weighted One Hand Pull Up?
- The most frequent error is using torso momentum (jerking): Rocking the upper body aggressively to initiate the pull relies on hip extension rather than the latissimus and rhomboids.. Controlling the 2 to 3-second eccentric lowering phase ensures maximal hypertrophic stimulus while shielding connective tissue.
- How many sets and reps should I perform on the Weighted One Hand Pull Up?
- For muscle hypertrophy and size, aim for 3 to 4 working sets of 8 to 12 repetitions at 70% to 80% of your 1RM with 90 to 120 seconds rest. For absolute strength development, prioritize 4 to 5 sets of 3 to 6 heavier reps with 2 to 3 minutes rest.
- What's a good alternative to the Weighted One Hand Pull Up?
- If you don't have access to a weighted, the Back Pec Stretch targets the same lats using body weight instead. This alternative replicates the same joint angle and movement plane while allowing you to train effectively with different available gear.
